Hi SilenceEngaged,

Don't worry about that.
The [VT.Detection] entry show up because this file was not present in VirusTotal database at the time of the scan. If you allowed the file to be uploaded, it won't appear anymore.
A process reported as unknown to VirusTotal is a hint it may be part of a polymorphic-code infection, it's a clue that can be really useful sometimes.

Regards.

Bonjour,
J'ai fait une signalisation de FP sur Roguekiller.
Mais je m'aperçois que je n'ai peut être pas fait au bon endroit.
Je l'ai déposé ici
https://forum.adlice.com/index.php?topic=3550.0
Dans l'attente de votre réponse
Pierre

Lately, roguekiller seem to occaisonally detect roguekiller's temporary installation/update files as suspicious, that seems odd. False positive or something else?
Attached details of such an occurrence

Hi Trombyl,

Welcome to Adlice.com Forum and thanks for your feedback.
This is indeed a false positive, most likely caused by an issue with RogueKiller latest version installer. We will investigate and fix this as soon as possible.

Regards.

Bonjour Pierre,

Bonne année à toi aussi.
SlimWare a été racheté par AVG Technologies et possède donc maintenant un certificat AVG. Cependant, il est toujours considéré comme PUP par de nombreux éditeurs, ce n'est donc pas à proprement parlé un FP.

Je te conseille de le faire désinstaller.

Meilleures salutations.

I am working topic over at Bleeping Computer where RogueKiller has identified some Intuit 2018 QuickBooks files as malicious.  Please see this link.  I think that these are false positives.

I purchased a 2-year subscription for RogueKiller Premium today and scanned my computer.  It is detecting a legitimate Cyberlink file as malicious and is also going after a Bitdefender uninstaller file, some detections that it is reporting as missing.  There is also a folder detection (C:\Program Data\Filter that I regard as a possible false positive.  Scan report attached.  See these URLs for analysis of the detections:

https://www.systemlookup.com/Drivers/10335-000_fcl.html
https://www.hybrid-analysis.com/sample/401cd6a87b9bec1f027c081ad23320c91d668dc5dc7a11226493e6aa387be6b7?environmentId=100

I run Bitdefender 2019 Total Security and Malwarebytes Anti-Malware Premium, and neither program has detected any of these files.

I just registered on your Forums today.  Thank you and have a great day.

Hi Phil,

Welcome to Adlice.com Forum and thanks for supporting us.
It's always a pleasure to see a fellow malware fighter.

The QuickBooks were detected with the [VT.Unknown] tag because they were not present in VirusTotal database at the time of the scan. This should not happen again if the user has allowed the files to be uploaded.

BitDefender uninstaller is detected since it's run from a temporary folder, RogueKiller detects it as [Suspicious.Path] because numerous malware are run from there.

What is the content of the Filter folder ?
Could you please upload the 000.fcl file with your next reply ? Please zip it first, otherwise the upload form will reject it.

Regards.

Curzon:

Thank you for your explanations, but if a file is tagged as [VT.Unknown], should RogueKiller default to removing it, if the user selects the clean?  Many users are going to think that RogueKiller has detected the file(s) as malware and be inclined to accept the default.

The content of the C:\ProgramData\Filter folder is one file: images, 12 bytes.  It is marked read-only and hidden.  The content of the file in hex is below
Code: [Select]
03 99 4B D4 20 A6 F1 7D    62 87 46 C4

I am attaching the 000.fcl file in zipped format as requested.

Thank you and have a great day.

I asked Tigzy's opinion about that and we are probably going to change this behaviour.

Additionally, the "Filter" folder and "000.fcl" file will be whitelisted shortly.

Regards.

Curzon:

Thank you for your reply.  Now that I have purchased RogueKiller Premium, I will be poking around and I will also be monitoring my Malware Removal Log topics even more closely, since, as a part of my standard anti-malware scans, I ask my users to run RogueKiller.  You can expect see me around in your Forums now that I am registered.

Thank you for looking into these issues for me.  Have a great weekend.

Hi Phil,

You are very welcome.
Please don't hesitate to report things that RogueKiller did not detect correctly.

Have a great weekend, too.

Regards.
